| Description | Journal: Iop Conference Series: Materials Science and Engineering Tin monoxide films were synthesized by sol-gel process followed by spin coating at the spinning speeds from 1000 to 3000 rpm. X-ray diffraction profiles of the films exhibits amorphous nature. Surface morphological and elemental confirmation of SnO films were studied by scanning electron microscope and energy dispersive of X-ray spectroscopy. The optical transmittance of the films had an increment from 60 to 72% with the increase of spinning speed from 1000 to 3000 rpm. The band gap of SnO thin films varied from 2.96 to 3.52 eV with an increment in rotational speed due to Burstein-Moss (B-M) effect. The estimated particle size from the optical absorbance spectra using effective mass approximation method is decreased from 23.6 nm to 11.6 nm with an increment in the spin speed from 1000 to 3000 rpm. |
